TDA8035 High integrated and low power smart card interface Rev. 3.1 30 June 2016 Product data sheet 1. General description The TDA8035 is the cost efficient successor of the established integrated contact smart card reader IC TDA8024. It offers a high level of security for the card by performing current limitation, short-circuit detection, ESD protection as well as supply supervision. The current consumption during the standby mode of the contact reader is very low as it operates in the 3 V supply domain. The TDA8035 is therefore the ideal component for a power efficient contact reader. 2. Features and benefits 2.1 Protection of the contact smart card Thermal and short-circuit protection on all card contacts V regulation: CC 5 V, 3 V, 1.8 V 5 % on 2 220 nF multilayer ceramic capacitors with low ESR Current spikes of 40 nA/s (V = 5 V and 3 V) or 15 nA/s (V = 1.8 V) up to CC CC 20 MHz, with controlled rise and fall times. Filtered overload detection is approximately 120 mA. Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, falling V V V REG DD(INTF), DDP Enhanced card-side ElectroStatic Discharge (ESD) protection of (> 8 kV) Supply supervisor for killing spikes during power on and off: threshold internally fixed externally by a resistor bridge 2.2 Easy integration into your contact reader SW compatible to TDA8024 and TDA8034 5 V, 3 V, 1.8 V smart card supply DC-to-DC converter for V generation separately powered from 2.7 V to 5.5 V supply CC (V and GNDP) DDP Very low power consumption in Deep Shutdown mode Three protected half-duplex bidirectional buffered I/O lines (C4, C7 and C8) External clock input up to 26 MHz Card clock generation up to 20 MHz using pins CLKDIV1 and CLKDIV2 with synchronous frequency changes of f , fXTAL/2, fXTAL/4 or fXTAL/8 XTAL Non-inverted control of pin RST using pin RSTIN Built-in debouncing on card presence contact Multiplexed status signal using pin OFFNTDA8035 NXP Semiconductors High integrated and low power smart card interface Chip Select digital input for parallel operation of several TDA8035 ICs. 2.2.1 Other HVQFN32 package (*) Compliant with ISO 7816, NDS and EMV 4.3 payment systems (*) for C2 version 3.
